What is the Apple Watch Series 9 45mm?
The Apple Watch Series 9 45mm is the larger case option in Apple’s Series 9 lineup, launched in 2023. It combines the S9 chip, a generous display, and Apple’s health and safety features in a design aimed at people who prefer a bigger screen for workouts, notifications and readability.
Key features and why they matter
- S9 chip — Faster app performance and on‑device Siri for quicker replies and better privacy.
- Larger 45mm display — More screen area for maps, messages and workout stats. Easier to read at a glance.
- Improved gesture controls — Simple gestures make common tasks faster without touching the screen continuously.
- Advanced health sensors — Heart rate, ECG and blood oxygen monitoring (availability depends on apps and region) help you track fitness and wellbeing.
- Water resistance and durability — Designed for everyday wear and water-based activities (check seller details for original specifications).
Which models belong to the Series 9 family?
The Series 9 family includes the 41mm and 45mm sizes. The smaller option is the Apple Watch Series 9 41mm, which offers the same core features in a compact case. If you prefer a larger screen for maps, reading or workouts, the 45mm is the better choice.
